Time to refuel for more boost?
 

Seems i am at a fulcrum point with my truck now. I cant really do anything else without upgrading the fuel system. I have been very leary of doing anything so far because there is really nothing above 42lb'ers that are plug-n-play. And there is still no high volume "drop-in" fuel pump for our fuel baskets. So here I am trying to decide what I should do........throw some 60's in there and try my hand with an in-line pump, throw some 60's in there and hack my fuel basket up to make it fit, or stick the larger pulley back on and enjoy what i have.

Couple questions....
-do they make any 60lb'ers that are plug-n-play yet? If not, whats the easiest way to make that swap? Harnesses?

-Is an in-line pump a better option than an intank one? Whats required to install the inline pump? Do i need special switches to engage the pump under boost only, or can it run all the time?

-Are 60's hard to tune? Whats the best 60lb injector for my application?

Some still dont believe how far i have pushed this truck on a "stock" fuel pump but its true and I am a little hesitant to do anything thats not made to fit. I still use this truck for camping and road trips and i dont want to sacrifice reliability for performance. I have never had any reliability issues what so ever to this point and want to keep it that way. I would rather have a mid-13's reliable truck than a high-12's/low-13's truck that i have to worry about when i drive a few hundred miles from home.

Wha type of injector plug do you have? ev1(old style)ev6(new style)or delphi(odd ball)there are a few connector conversions out there these days,so far the best ones are the newest offered by ford racing,go to there web they have em pictured,no splicing no hacking....
60lb injectors can be tuned easily,the inline pump I believe is a band aid(or quik fix)IMO,an intanke pump is better IMO.
The fuel delivery system is what will fail you before these A/M pumps will Also IMO.
I have been working on an alternative fuel pump system similiar to an old buick turbo gn intank twin set up(dual walbro's) relayed and set with a hobbs switch to energize the second pump At a set boost.But that has had some issues,still working on it though,My truck will likely be the test mule,again I think the fuel lines are going to be the weak link.

I have an in-line pump advertised as being 1000 HP capable. With a stock pump in the tank, I was running out of fuel at higher Rs. I got a Walbro 255 l/hr kit from Texas Speed. I did not have to butcher the bucket. Be warned the instructions don't apply to trucks, and the adapter harness that comes with it is only good for cutting and splicing the pump-end plug into the stock harness. But appears that it'll be a long time before I run out of fuel again.
I added a relay for the in-line, tying the coil wire into the stock pump's relay coil wire.
As far as I know, only the IFR needed to be changed for the 60 lb'ers.

If you have a return fuel system then the 60's should be easy to tune. If you are like me and numerous others with a returnless fuel system then they are not quite as simple.

Im thinking about these...

racetronix L107FM

anyone have a link to the harness adapters?

Whats the best intank pump to go with....looking for reliability here and I am not opposed to spending a little more. I have heard mixed results about the Walbro 255. I am going to search for an intank pump replacement thread, if anyone knows of a specific one, please post up.

you have return? Hmmm. If you are return, the inline is a bandaid with smaller inj'ers. But IMO is fine if you have the 60#'ers at your HP/weight level. I say if you are gonna do the fuel, do it right with injectors and an high flow pump, albeit intank or inline. The ultimate is like mentioned above, dual 255's intank. But you might as well build your own setup though. I have the 60's, inline, and I put a 255 in my tank (chopped up my basket a little) and I haven't logged my IDC's since.

the 60's aren't too bad to tune, you have a lot more cubes than the rest of us, yours should be easy to tune. An IFR change only maybe.

Yes, i got the return style system. I think Im going to go with an inline and the stock intank pump. Thanks for the link SuperSub.

Be careful with that inline/stock in-tank setup. I burned up two inline pumps in two years because the stock in-tank pump couldn't supply fuel fast enough to the inline. I personally would bite the bullet and do the in-tank pump.

I hear ya...I just dont wanna rip up my fuel bucket. I have also heard that the intank pumps dont fit right in, they need to be modified and you need to always keep a 1/4 tank of gas in it or you will have problems. Why the frick cant someone just develop a OEM style high volume pump for our trucks? Whats so damn hard about that?!?

I get the feeling that you think I am just an internet typist.
I put an aftermarket pump in my tank a few years ago and ruined the bucket. I got tired of keeping the tank topped up, and put a stock pump in with an inline.So the pump I got from Texas Speed fit in the bucket, I would have found an alternative if'n it didn't. I was thinking of dual in-tank, but it would have been an extra bucket assembly, maybe it could be cable-tied to the first, with both buckets in the tank, and the top up for access.

I swear I don't mean this to be funny, but seemed for awhile that's all you heard about was dead inlines. Same with mine. I replaced them back to back. 3 total if I remember correctly. Then I modded my intank, no prob's since. However I am not putting 50K miles a year on it anymore either. Pics are posted backwards, completed on top, started at bottom.

Nah, i just am having a hard time with all these posts Im sifting through telling me that the baskets had to be hacked up. DId the pump you bought drop right in, with the sock on the outside of the bucket like the stock pump does, or did you have to put the sock on the inside? Does your pump have 2 inlets like the stock pump? Do you have an issue with running out of fuel when below 1/4 tank under hard excel? If they would make a 255l/ph thats the same size and configuration as the stocker everything would be fine.

......all that plus I dig your sexy posts Mike.

Is that petrol rated duct tape Dewy? And thats an awful big jar of vasoline you got there too!

If I were in your situation I would add the auxillary pump and bigger injectors first. No reason to mess with the stock pump if it's working. If you don't have enough fuel pressure by doing that, then change it.

yep, somewhere up there in the posts I say the same thing (I just want to appear like I agree with Zip :P) but there are my pics if you want a hack project for what remains of the winter.

Thats kind of my thinking too, only because if the aux pump fails, I can still get fuel from the stock intank pump. But if something goes wrong with the intank pump......1-800-towme

I knew there was a good reason I didn't stay after that get together at his place last year. :eek2: :jest:

What do you mean? That is a travel size.

I've had inlines die and you can still run off the stock intank pump but, the inline creates such a restriction that you can't accelerate much at all. It will run and get you home or to a shop though.

The sock is inside the bucket. It has one inlet. I haven't let the fuel run that low yet, but there is no reason that the pump should suck air, all the check or flap valves in the bucket are operational.

My twin in-tank setup has both socks outside the bucket, flat against the tank bottom. Food for thought. I'm very happy with it so far.

What pump does the intank take? Mine is a GSS340 Walbro does the return setup take the same pump?

Got pics?

FWIW. I have the stock in tank. Never touched. The inline that came with the Magna kit. 2-3 years now. Only time I drop fuel pressure is 1/4 tank or less. 60# injectors sitting on the work bench waiting for me to install. If either pump fails they will be replaced with the same.

Hey back off Mike, this is my thread.

Hey thunder, you got any pics?

:)

is the pump that comes with the magnacharger the same gss340? if so in there instructions it does not show them hacking anything up at all. http://www.magnacharger.com/pdf/manu...00-2003-06.pdf

Those instructions are for a returnless system, our bucket is different.

Unfortunately no, I don't have any pics. It's a Racetronix twin in-tank setup. The bucket was cut up significantly to fit two pumps inside, but both of the socks were outside the bucket and resting against the bottom of the fuel tank. It came with a plug and play harness and a hobbes pressure switch to turn the second pump on at 4 psi. It is 1000+ hp compatible supposedly. I have 96# injectors, and with my 408 at 15 psi I see almost 70psi fuel pressure and a max injector duty cycle of around 60%. Racetronix may have more info they can give you if you get in touch with them directly.

Im in the same boat, stock intank, 255 inline. works fine.

Here is what im thinking. I was sent a link to a set of injectors (good price) that i plan on picking up. I have a Walbro 255 in-tank pump in the garage on the shelf I bought with the blower but never installed it. I think I am going to pick up an in-line pump with the clean install kit from Summit with the braided lines and stuff so it looks nice and clean. If i have problems with the in-line, i will pop it off and try my luck with the in-tank pump. So my next question is whats the best in-line pump out there?

Walbro?
Bosch?
Holley?

I have seen Holley stickers and packaging with Walbro pumps and viceaversa. As a matter of fact look up at my pics, red top, that was packaged in a Holley box and wrapping. It has a big "W" on it with GSS in the part number, Walbro. Pick your poison.

Good priced injectors flow matched?

email from guy at link. Hello! Thank you for your interest, we appreciate your inquire. I'm not familiar with that company or where they purchase their injectors but we buy direct from Mototron/Siemen Deka and have plenty in stock. These are flow matched to within 2% of one another.

not sure if it helps but they gave me a military discount also.

I put the 255 pump in my tank with no mods or anything all I had to do was cut and connect the two wires and hook the hose up and it dropped right in the system. Mine was almost exactly the same size and everything. I have had zero problems but I do have the returnless type.

yes sir.

I'm on 60lb motrons in the boosted vette, and in the suburban. Vette has stock intank, monster inline, y-d into the stock line then into aftermarket billet rails and regulator and will support 750-800 at the wheels in a vette with meth. The sub is a stock intank, nothin inline, just a boost a pump, with 60 lbers and was on the edge of fueling with 537 at the wheels on the truck.

here's pictures of the spacers and adapters used on the truck as well as LS2 format motors....My LS6 in the boost car is plug and play drop right in, oh wait, now i'm not sure, with the rails etc. wiring wise it plugs, I'm not sure if the rails are machined and drilled accounting for the spacer used on the LS2 and sub.

With the tahoe, I put a 255 lph drop in (its old school return style etc.) even an inline forced induction booster pump, was fine with teh 502 (well had to gut the inrail regulator and put an external one on because it bumped the pressure up) hit the shot and it'd go lean. Eventually wound up putting a stock intank sender (you know the one rated for a 255 hp 5.7) and it fuels the 502 fine on motor, adn put a cell and the inline pump with the regulator etc. that runs only when the juice is activated. So just throwing in a monster pump make sure you check your pressure, might need to adjust it with more flow.

here you go for the inline install.
one of the photos include all of the part numbers from summit.
very easy to do.

Cool, thanks Pappy. I ran across that a few days ago when I was searching. You saved my some time having to look for that again. :chug:

What about a voltage booster on the stock pump? They can be setup to only boost voltage under boost. Might be another option.

thats exactly what I have on the suburban, actually thats ALL I have on the sub. a MSD boost a pump hits the pump with something liek 16v when it sees boost normal voltage otherwise. Of course stock pump with 60 lbers I'm out of fuel around 550 at teh wheels. Next step for me is a bigger intank.
